SYNOPSIS
High pressure maintains dry weather late this week into early this weekend with temperatures rising to above normal levels. A strong frontal system has the potential to bring a period of steady rain, gusty southerly winds and potential for coastal flooding along the southern coastlines later Sunday night and into early on Monday. Turning drier by Monday afternoon with a brief shot of colder air for Monday night, but temperatures look to rebound back closer to seasonable levels by next Tuesday and Wednesday.
NEAR TERM /UNTIL 6 PM THIS EVENING/
1235 PM update...
Cloud cover a bit more extensive this afternoon so lowered temps a bit with highs upper 20s to lower 30s which is up to 15 degrees below normal. Weak low level warm advection ahead of a warm front in central NY has led to some snow showers across eastern NY which will try to spill into the Berkshires this afternoon. However, dry low levels with dewpoints in the teens will likely limit any precip to a few flurries.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/
High pressure should be more overhead tonight, before moving offshore Friday. Dry weather continues trough Friday. Clearing skies tonight and light west winds result in better radiational cooling conditions, with below normal temperatures continuing.
More sunshine and winds shifting to the south Friday expected to lead to a return to near normal temperatures.
LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/
Updated: 3:20AM
* Quiet, mild, and dry weather Friday night through the first-half of Sunday. Afternoon highs could approach 60 degrees Sunday ahead of a robust weather system.
* Potentially a multi-hazardous weather system late Sunday night into Monday could bring strong winds, soaking rains, coastal flooding and erosion, in addition to dangerous marine conditions.
* Quieter and cooler Tuesday and Wednesday.
Friday Night through Saturday Night:
No significant adjustments to this part of the forecast. High pressure anchored to the south and mid-level ridging aloft allows for a tranquil conditions. Friday night into Saturday morning temperatures range between the upper-20s and lower-30s. Clear skies early Saturday gives way to increasing clouds due to WAA bringing higher PWATs/moisture to SNE. That said, Friday night, Saturday, and Saturday night remain dry. Afternoon temperatures on Saturday reach into upper-40s and low-50s. As for the overnight temperatures those range between the mid-30s to low-40s. Winds are S/SSE less than 10 mph.
Sunday through Monday:
A rather robust system could bring multiple hazards late Sunday night through Monday. As we have been advertising, there remains potential for the following, strong wind gusts, dangerous marine conditions, heavy rainfall, and event he possibility of coastal flooding and beach erosion. First, let us break down the latest 00z guidance.
The latest deterministic guidance suggests the mid-level trough is in more of a neutral state versus a negative tilt. But what does this mean? Negative tilted trough, oriented SE-NW, suggest a signal for potential intensification of the system. Now a neutral state or no tilt to the mid-level trough would suggest a lesser chance of intensification. Given there is still 4-5 days between this forecast and the arrival, there is pounds of time for changes. And there has been a slower trend for the onset of precipitation, will discuss that more in a moment. Otherwise, guidance trends remain in fairly good agreement.
Winds - Feel a bit like a broken record, but there is building confidence a strong wind event could impact southern New England late Sunday night into early Monday. Deterministic guidance remains consistent with a strong LLJ crossing southern New England with winds aloft at 925mb ranging between 70 to 85 knots. How much will make it to the surface will remain the big question. ECMWF ensembles have a greater than 70 percent probability for wind gusts to exceed 50 knots over the islands and Cape Cod. And a low probability of 10 to 20 percent of gusts exceeding 64 knots across the same area. A bit closer to the I-95 corridor from Boston to Providence these probabilites do drop off. The are high probabilites, greater than 80 percent, gusts could exceed 34 knots. Then probabilities between 30 to 40 percent for gusts to exceed 50 knots. There are still other variables like a temperature inversion above the surface and does that limit the amount of wind mixing to the surface. We will continue to monitor and post wind-related headlines as confidence grows.
Rain - Onset for rain has shifted later into Sunday, likely after sunset rain arrives from west to east. As for how much rain, still too soon to tell, but the global ensembles continue to signal for soaking rains. ECMWF is the wetter solution with probabilites between 70 and 90 percent across most of the CWA. GFS has a bit of a tighter gradient in their probabilites of an inch, west of Worcester, 80 to 90 percent, lower probabilites of 30 to 50 percent Boston to Providence. WPC continues to keep parts of the CWA under a marginal risk for excessive rainfall. As mentioned before the amount of leaf debris may allow for poor drainage flooding.
Marine - Waters off southern New England are squished between two pressure system, an approaching low to the west and high pressure to the east. Gales to storm force winds possible along with large seas across the waters, with more of a focus on the southern waters that could linger well into Monday night.
Coastal Issues - There remains the possibility of beach erosion due to large waves crashing onto area beaches and coastal flooding. For what it is worth, the Steven's Institute shows the potential for flooding at the top of Narragansett Bay at Providence. There still remains a widespread in the guidance, the 5th percentile keeping levels well below flood stage, while the 95th percentile would suggests a high-end minor flood event to low-end moderate flood event. This will all come down to if the max surge coincides with the high tide during the predawn hours of Monday.
In addition, will be quite warm for early December, highs Sunday are in the mid-50s to 60 degrees. Behind the system temperature cool off rather quickly, highs Monday afternoon are low to middle-40s.
Tuesday and Wednesday:
A break from the active weather with drier and cooler conditions.
Highs are generally in the low to middle-40s, overnight temperatures are in the upper-20s.
AVIATION /18Z THURSDAY THROUGH TUESDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
18z update...
Through 00z... VFR. WNW wind around 10 kt.
Tonight and Friday...High confidence.
Mainly VFR, but will have to watch for some lower MVFR cigs moving in from the west tonight. These lower clouds may impact western MA/CT tonight into Fri morning. Light to calm wind, trending to light S Fri afternoon.
Friday night...Moderate confidence.
Main uncertainty is whether some low clouds develop overnight Fri night with MVFR cigs. Expect a mix of VFR/MVFR cigs.
KBOS Terminal...High confidence in TAF.
KBDL Terminal...High confidence in TAF.
Outlook /Saturday through Monday/...
Saturday through Saturday Night: VFR.
Sunday: Mainly VFR, with local IFR possible. Windy with gusts up to 35 kt. Chance RA.
Sunday Night: Mainly MVFR, with local IFR possible. Strong winds with gusts up to 45 kt. RA.
Monday: VFR. Strong winds with areas of gusts up to 40 kt. RA likely.

Thinking Small Craft Advisories may be able to be let go earlier than current timing. Otherwise, light winds and seas expected across the waters through Friday.

Friday Night through Saturday Night: Winds less than 25 kt.
Sunday: Low risk for gale force winds with gusts up to 35 kt.
